476 BRITISH ORIBATIDJ;. 



Average lengtli of legs (second pair) about '11 mm. 



Average length of legs (third pair) about '10 mm. 



Average length of legs (fourth pair) about "13 mm. 



A very small species, having a considerable resem- 

 blance to E. cymha, but which could not be mistaken 

 for it, even on a cursory examination, by anyone 

 acquainted with the last-named species. 



Colour light oak-brown, getting much darker towards 

 the posterior margin of the abdomen. 



Texture rough and dull. 



Shape short-pyriform. 



Cephalothorax rough, with irregular raised dots or 

 rugositeSjbut without any regular ma/rkings; it is sharply 

 divided from the abdomen by a deep narrow sulcation. 

 Rostrum rounded at the tip, but much narrower in 

 proportion than that of E. cymha. Rostral hairs short 

 and curved, springing from small projections. No 

 trace of lamellfB or translamella. Pseudo-stigmata 

 rather large, at the extreme edge of the body. Pseudo- 

 stigmatic organs with very short peduncles, and large, 

 almost globular heads. Interlamellar and lamellar hairs 

 very small, almost rudimentary, but thick in proportion 

 to their lengtli. There are two small projections on 

 each side carrying the legs. 



Legs short, fourth pair scarcely reaching the hind 

 margin ; roughisb ; femora of the two front pairs with 

 short peduncles. Tarsi large ; the proximal parts 

 approaching a globular, or very short pyriform, shape, 

 but ending in a straight rod-like portion carrying the 

 claws, which are large and tridactyle, almost but not 

 quite homodactyle. Most of the joints have two or 

 three short, sharply-curved hairs ; the tarsi are densely 

 clothed with fine hairs, and the tactile hairs are well- 

 developed. 



Abdomen widest near the posterior margin, having 

 a truncated appearance ; it slopes downward from the 

 anterior to the posterior margin ; the latter seems 

 truncated perpendicularly as well as horizontally, so 

 that the hind edo-e is thick. The median line is much
